Frag Maps just shared: “The Construction Site”

This material was posted on patreon by Frag Maps

This map was a real challenge because of all the crazy details that went into it. I knew I should have pulled back on the details early on but seeing the potential this map had to offer, I just had to keep going. I’ve been told by quite a few gamemasters over the course of my map making journey that the details I put in inspire fresh ideas. Thus, this always sticks at back of my mind with every map I create.  

The Relic Variant

The initial idea with this map variant was this: demolition and reclamation of the land occupied by the slums (see “Cyber Slums” map) was in progress when the construction firm discovered a portal / doorway to a hidden underground facility. 

However, I also wanted the variant to offer more flexibility than just a doorway to another place. I was thinking maybe an alien artefact that was a huge threat to not only the players but to the city as well. 

In the end, I opted for a simpler 2-in-1 solution: an alien pyramid structure generic enough to serve as either an artefact or a doorway to another place. 

Those of you who’ve watched Jeremy Renner’s movie (“The Arrival”) will know where my mindset was during the concept stage. Here is a fun scenario idea: Have your players try and figure out how to gain access into the pyramid, while they get swarmed by enemies coming in from all angles.
